【 摘 要 】

This study presents a model predictive control (MPC) considering transformer DC magnetic bias for a reduced matrix converter (RMC). The control scheme selects the switching state that minimises the error in the output current and input instantaneous reactive according to their reference values; furthermore, the pulse sequence in MPC has been re-distributed to suppress the DC magnetic bias in transformer for RMC. MPC also presents stronger immunity to the influence of abnormal input voltage than bipolar space vector modulation strategy. Moreover, the simple performance comparison between RMC and pulse-width modulated rectifier + dual active bridge was provided. The feasibility and validity of the proposed control scheme in an RMC has been verified by simulation results.
